The black holes of Einstein's theory of relativity can be completely described by just three properties — how heavy they are (mass), how fast they rotate (spin rate), and how much charge they possess. Since two black holes that share these properties cannot be distinguished, regardless of how they were created, black holes are said to have no hair, i.e. they have no additional attributes that can be used to tell them apart. In recent work, our CSCDR faculty Dr. Khanna and his collaborators show that nearly extreme black holes attempt to grow hair .. but ultimately fail!

Today, major advances in nearly all types of science and engineering are aided by computation. Indeed, high-performance computing (HPC) or supercomputing is now considered as the third pillar of scientific discovery alongside experiment and theory. Massachusetts universities (both public and private) excel in this emerging area and have a strong and diverse group of computational scientists and engineers across each campus.

UMass Dartmouth’s Center for Scientific Computing & Visualization Research (CSCDR) organized and hosted “HPC Day 2016” on May 17th — a conference to showcase compute intensive research from researchers in this community from all over Massachusetts. There were participants from: Northeastern University, Boston University, MIT, UMass Amherst, Dartmouth & Lowell and even industry. A special poster session with awards for student projects was included as well. This conference was a follow-on event from the inaugural “UMass HPC Day” conference hosted at UMass Dartmouth in 2014.

The event featured a total of 11 talks with topics ranging from engineering microbial systems to renewable energy extraction from the ocean. Over 145 attendees registered in this event in total and 30 student posters were presented. More details on the program may be found on the CSCDR website. Six awards were granted that were made possible via generous donations by Nvidia, SIAM and MathWorks. The conference lunch was sponsored by Microway Inc.

The keynote speaker was Dr. Jeremy Kepner from MIT Lincoln Lab who gave an fascinating and deeply engaging lecture titled “Interactive Supercomputing for High Performance Data Analysis.” The event also featured an interactive Education Panel that included stakeholders from industry and academia to discuss issues associated with HPC education and training.

The CSCDR also used this event to debut a new innovative, prototype supercomputer built entirely of mobile-devices (in particular, Nvidia Tegra X1 components used to build tablets) dubbed “Elroy”. The system’s total compute capacity is 16 Tflop/s and consumes just over 300W total power. The unique feature of this 32-node system is its extremely high power efficiency -- an order-of-magnitude larger than traditional systems. This was made possible by leveraging recent, very significant power-efficiency related advances that have been cleverly engineered into current cell phones and other mobile devices (to prolong battery life). Power-efficiency is a limiting feature in large scale supercomputing as well, due to the expense associated to large power consumption and corresponding cooling requirements. Elroy demonstrates a unique approach towards potentially meeting this challenge. This project was a result of a collaborative effort between the CSCDR and UMass Dartmouth CITS. The CSCDR has a history of developing innovative supercomputers from using gaming consoles to more recently, using video-gaming graphics cards.

The CSCDR provides undergraduate and graduate students with high quality, discovery-based educational experiences that transcend the traditional boundaries of academic fields, and foster collaborative research in the computational sciences. The CSCDR's computational resources are being utilized to solve complex problems in the sciences ranging from the modeling of ocean waves to uncovering the mysteries of black hole physics.

Please check the conference webpage fore more details including sample pictures of the day.

The CSCDR is in the process of accepting an in-kind "SwitchBlade" grant from Hewlett Packard Enterprise (HPE). The granted equipment consists of an HP SwitchBlade Center chassis that contains the required power and networking infrastructure to support up to 16 high-end blade servers for high-performance computing. Two servers are included in this grant, leaving room for straightforward and low-cost expansion in the future. The granted hardware is valued at $95K.

With the two included servers, the system currently has 64 Intel Xeon E5 processor cores, 512 GB main memory, 2 TB storage connected via a high-speed network.

This grant is a result of efforts made by Glenn Volpe (HPE) and CSCDR Associate Director Professor Gaurav Khanna on behalf of the CSCDR. The SwitchBlade system is currently being leveraged to attract new top-notch faculty to the university. These faculty and their students will be affiliated with the CSCDR.

The University of Massachusetts Dartmouth’s Center for Scientific Computing & Visualization Research (CSCDR) has received donations of two supercomputers that were built and used for mining Bitcoins.

Bitcoin is a digital currency that has garnered a lot of popular media attention recently. In addition to buying a Bitcoin, that runs for around $250 these days, one can also "mine" or generate it, using a powerful computer by solving a cryptographic puzzle. However, Bitcoin is designed in a way that the more mining that occurs, the harder it becomes to mine via an exponential increase in its complexity. So, a powerful computer today that could mine effectively, in a few months would be essentially worthless due to the rapid increase in Bitcoin's complexity. Now, there are investors that built very large supercomputers solely designed to mine Bitcoins — some spending even millions of dollars to build these systems — that are now largely useless, at least from the Bitcoin mining perspective. These machines are sitting idle or simply turned off.

In December 2014, the New York Times’ Laura Parker covered Prof. Gaurav Khanna’s novel use of PlayStations for his computational research in black hole astrophysics in a full length article. Two Bitcoin mining investors read the story and decided to donate their large supercomputers to the university campus for enabling research productivity further in the CSCDR.

The two donated systems are very well suited to enable research in the CSCDR. The key feature of both systems is that they are GPU-accelerated i.e. they use high-end video-gaming graphics-cards to speed up numerical calculations significantly. These make the systems excellent for a large variety of scientific applications. The larger system amongst the two was built in 2012 at cost nearing a million dollars and consists of 180 servers installed in 10 racks, integrated tightly over a fast network. Its replacement cost today could be in ballpark of $400,000.

The donor, Daniel Driscoll of San Francisco shares his thoughts on his donation: "This past winter during my morning commute, I stumbled across an article about a research project that recently used a networked super computer modeling the physics of black holes. Having grown up in the 80's next to the shuttle launch pad in Cape Canaveral, Florida, I remain an ardent fan of all things space. What struck me as even more interesting was how Professor Gaurav Khanna had created this super computer from now derelict Playstation 3 consoles. Being now part of the game industry, I was all too familiar with the transition of Playstation fans to the new flagship, the Playstation 4, and had myself done a few experiments to understand the potential uses for the no-doubt countless number of old Playstation 3's likely going to the trash. One such experiment involved a private venture to explore and understand the Bitcoin craze of 2013, a venture that ultimately proved fruitless but left me in possession of not just several Playstations, but all also a large collection of what I had deemed a more effective array of server computers. Now that bitcoin has come and gone for the hobbyist farmer, Professor Khanna and the University of Massachusetts Dartmouth has provided me an opportunity to join those explorers I once grew up with, if only in my own small way."

The donor of the smaller system chose to stay anonymous; the university respects their privacy and therefore will not comment on any further details.

Prof. Sigal Gottlieb, the Director of the CSCDR remarks on how the donation would impact the research productivity of the Center: "The new computational cluster will be a tremendous addition to the resources of the CSCDR. The new system will triple the computational power available to us, significantly increasing our research abilities. All CSCDR members, and our students, will benefit from this valuable computational tool as we continue to expand the scope and range of the computational problems we are attacking."

Moreover, multiple new faculty that are joining the university would also be able to utilize the same resources to jump start their research programs. In the long run, the large computational resources of the CSCDR will help attract top talent (both faculty and students) to the campus and thus strongly enhance the campus’ research profile. College of Engineering and Campus’ IT services have worked hard and supplied resources to accommodate this significant sized supercomputer, and are committed towards ensuring full utilization of the system.

The CSCDR provides undergraduate and graduate students with educational experiences in supercomputing and fosters collaborative research in the computational sciences within the university and with researchers at other universities, national labs, and industry. Khanna serves as associate director of the Center.

The RC5 cryptography challenge (Wikipedia) was originally started by RSA Laboratories as a worldwide contest to decode a cipher by finding the secret cryptographic key using a brute-force approach. The 72-bit version of the same contest continues today, conducted by distributed.net -- one of the oldest open public distributed computing projects on the internet.

Professor Gaurav Khanna of the Physics Department and associate director of the Center for Scientific Computing and Visualization Research (CSCDR), and computer technician Glenn Volkema, have built a novel supercomputer using consumer video-gaming components (over a hundred Sony PlayStations and multiple AMD Radeon graphics-cards) that has enabled the campus' rank to soar to the absolute top of the RC5-72 contest participant list (link).



This unique system is generating approximately 50 billion keys per second and is slated to have a 1 in 10 chance for winning the contest all by itself!

The supercomputer has been built to study various astrophysical problems associated to binary black hole systems and gravitational radiation. Physics Department graduate students, Tyler Spilhaus and William Duff are already utilizing the system extensively for their research projects in this context. In addition, Computer and Information Science major, Violet Pfeiffer will be using the system to study different aspects of cryptography and cybersecurity.

Space.com has published an article featuring CSCDR Associate Director Gaurav Khanna's research. Dr. Khanna's work focuses on using computational methods for astrophysics, and seeks to understand how black holes interact with other stars and other black holes.

See the full Space.com story about Dr. Khanna's work, which incorporates high-performance supercomputers, advanced computational algorithms, and state-of-the-art astrophysical modeling.

The Air Force Research Lab (AFRL) at Rome, NY has granted UMass Dartmouth's new Center for Scientific Computing and Visualization Research (CSCDR) four full racks (176 units) of Sony PlayStation 3s for research computing. UMass Dartmouth pioneered the use of PS3s for astrophysics research back in 2007 when Prof. Khanna of the Physics Dept. created a compute cluster of 16 PS3s and ran his black hole research simulations at supercomputer-level performance. In 2011, the US Air Force commissioned a similar, but much larger system (1,760 PS3s) called CONDOR for a wide range of military and academic uses.

Under a federal CRADA agreement, AFRL has now granted a portion of CONDOR to UMass Dartmouth for further exploration of such novel computational technologies for the purposes of scientific high-performance computing. See some pictures of the cluster: Picture 1, Picture 2, Picture 3. For more details, see The PS3 Gravity Grid.

The CSCDR announces a workshop series for the software packages Pseudopack and WENO-pack. The workshop will be held on March 5 and 6, 2014, and will be facilitated by Professor Wai Sun Don from the Ocean University of China. Details can be found on the workshop homepage
